To'aZZ whom it may concern.'

Be it known that I, RICHARD HENRY` JOHNSON, a citizen of the UnitedStates, residin at Creston, in the county of Lincoln and tate ofWashington, have invented a new and useful Improvement in Route-indicators, of which the following is a specification.

This invention relates to improvements in route-.indicators for use onvehicles, such as automobiles, to indicate `mileage and variations ofroad direction to the driver.

@ne of the objects of the invention is to associate or combine a routeindicator ywith a speedometer in such a manner as to drive both from therunning gearby one shaft connection.

A further object-is to provide a web having Aregularly spaced mileagegraduations and a line of route so distorted in proportion with respectto the road traveled as to bring certain points or cities inaccurateregistering proximity to the mileage gradumovement toward the finalpoint of destinaf tion.

Other features and objects of the invention will. be more fullydescribed in connection with the accompanying drawings and will be moreparticularly pointed out in and by the appended claims.A

1n the drawings z-Figure 1 is a face view of a combined speedometer androute indicator embodying one form of my invention. Fig. 2 is a viewsimilar to Fig. 1 with parts broken away and parts in section, forclear# ness of illustration. Fig. 3 is an end view of the device shownin Fig. 2. Fig. 4 is a view in elevation of a portion of the web. Fig.`5 is a detached view of one of the spindles for one of the web spools.Fi 6 is a fragmentary sectional view indicate by line 6-6 of Fi 2. Fig.7 is a sectional view on line 7 of Fig. l6. Fig. u8 is a sectional viewon line 8--8 of Fig. 3.

Like characters of reference designate similar fparts throughout thediferent figures O the drawings.

bined with a speedometer it may be einbodied in a casing 1, having afront -face 2 provided with an opening 3 through which the indicator web4, may be viewed. One shaft may be employed to operate both theindicator and the speedometer and such shaft is indicated at 5 and maybe connected for operation from the running wheels in any desirablemanner, not shown. A bevel gear 6, on the shaft y5, meshes with a bevelgear 7 to transmit rotary motion to a worm shaftS. Said worm shaft 8 isjournaled in a bearing 9 and carries gear 7 on one end and a worm 10 onthe otherl end. Worm 10 forms one unit of al reducing gear train whichincludes a worm wheel 1l with which the worm y1() meshes and which ismounted upon a shaft 12. A worm wheel 13, mounted on shaft 12, mesheswith a worm disk 14: on shaft 15. Shaft 15 is journaled in bearings 16and carries a' small pinion-17 meshing with gear wheell 18. Gear wheel18 is l' mounted on a spindle driving shaft 19 which is longitudinallyimmovably but rotatively journaled in one of thebearings 16 and abearing 20. The end of spindle drive shaft 19 is toothed to clutch withthe toothed end 21 of a primary or driving spool spindle 22. A plate23fset flush with one end of the casing incloses anopening therein whichserves for access to the interior of the casing. Suitable fasteningdevices are provided for holding the plate in a closed position, and asshown in Fig. 8 said devices .comprise interior fingers 24 mounted onspindles 25 rotatable in the plate 23 and having externally disposedfinger levers 26 mounted thereon.

The lowery spindle 22 is .journaledI 1n the plate 23 andthe latter isprovided with a hub 27 having a shouldered margin 1n which va spindlebearing disk is seated and the spindle 22. is provided with an annularange 29 for engagement with said disk.v A spring 30 is interposedbetween said vdlsk v29 and the plate 23 to normally hold the spindle 22in the Aposition shown in Fig. 6. The spindle 22 is provided with an.annular groove 31 which is so located as to liewithln the outside faceof the plate 23 when the spindle 22 is in the position shown.

lmurled thumb nut 32 is mounted on the end of spindle 22 for, eitherrotative or long itudinal adjustment thereof. A retainer 33 is pivotedat 34 on the outer lface of plate 23 and is provided with a notch 35 forengagest A ment with the groove 31 when the lattery movementJ will serveto disconnect the spindle 22 from driven connection with the spindledriving shaft 19 so as to throw the indicator out of gear. In theadjustment shown in Fig. 2 however, the spring 30 holds the spindle 22in driven connection with the shaft 19. The spindle 22 is provided witha key 36 for lnon-rotative engagement with the primary spool 37 ontowhich the web 4 is wound from a secondary spool 38. The

secondary spool 38 is keyed to a secondary spindle 39 which is journaledin a hub bearing 40 formed onptheA plate 23. The spindle 39 is providedwith a, knurled thumb disk 41'- and the spool 38 is held on the spindle39 by any suitable bearing means indicated at 42, fixed to the casing. Asimilar bearing means 22', fixed to the casing, supports spindle 22 at apoint at one side of its clutch engagement with driving shaft 19.

It will be understood that each map will be' attached totwo spools andthe different maps will be provided' for the different routes which itis desired to traverse. removing the plate 23 the spools can be removedfrom the spindles and another map with its spools inserted.I

A starting index is indicated at 42 and the web 4 is drawn downwardly inthe form shown, abreast of said index. In making up the map, on the web4, the graduations 43 will be regularly spaced apart and the map will bedriven at a proportionate speed by the gearing herein before describedso that. as the map traverses a distance equal to the distance betweentwo numbered graduations, the vehicle will have covered a road mile.`line 44 will be designated by canting lines 45, 46 and 47. In order tocompensate for lateral turns of the main road the map at suchdesignating points will be distorted, as

l by contraction, so that the lineal distance between vtwo 'citydesignating points can be located adjacent the proper designation ofactual mileage.' Ihus in making up the map, the cities'will be locatedtheexact distance equal to the length of road to be traveled y1n goingfrom one to the other, including all turns of the road and left andright swings, the map being distorted from true proportion as little aspossible to develop the correct ratio with the mileage indicay the roaddeflects from the main line and thev .distance from X to Y wouldnecessarily tions. Above the town of Greenacres, asindicated at 48, themain line is dotted to indiv cate a' swing north and south, or in otherwords, .a deflection from the east and'west main line.4 At a point abovePine Croft,

show longer on the map because the map would necessarily continue tomove down- Any roads leading from themain ,Liemers Wish to be limitedthereto except for such l limitations as the claims may import.
